CAR CONSTRUCTION.

Applicaties mea nay as, 192s. serial No. 112,479.

This application relates to a new and imroved car construction and more particuarly to a car wall construction especially adapted for use iu connection with cars of the ho per type.

In tie construction of cars of this chai`- acter the Aload containing vcapacity of the car hoppers is limited by the clearance diagram of the railroads together with the standard height of the top of the hoppers. The hopper walls are constructed of metal plates and in order to provide the requisite strength the plates are supported by verti-` cally extending stakes located along the side and end walls. In constructions where the stakes are located upon the outside of the car walls a certain amount of capacity is lost depending upon the depth of the stakes. In the endeavor to secure'added capacities some cars have been built with the stakes upon the inner side of the car walls. This construction results in interference with the free discharge of the material and has the further serious disadvantage that the stakes tend to rust and thus become weakened. The material carried b the cars wears against the stakes in loa ing and unloading and protective painting is worn off, and due to moisture in.. the load the stakes rapidly deteriorate in strength.

It is an object of the present invention .to provide a car wall construction in which the wall supporting stakes are located exteriorly of the car wall and in which the Wall is so formed intermediate the stakes as to insure a maximum load capacity.

It is an additional object to provide a construction of this character in which the wall serves to reenforce the stakes and to protect them against wear and injury.

It is a further object to provide a construction adapted for commercial manufacture by the usual types of car building machinery.

Other and further objects will appear as the description proceeds.

I have illustrated one preferred embodiment of my invention in the accompanying drawings, 1n which- Figure 1 is a somewhat diagrammatic side elevation of one half of a hopper car;

Figure 2 is a horizontal section on an enlargied scale taken on line 2-2 of Figure 1; an

Figure 3 is a vertical section taken on line 3-3 of Figure 1.

'Ihe car comprises the car frame 11 which v is supported upon any usual type .of wheels indicated at 12 by any usual car truck construction. The car shown is a standard hopper type provided with the sloping end Hoor 13 and the' sloping centi-al floor 14. Any usual type of hopper doors and door pperating mechanism may be provided at The side walls of the hoppers comprise the vertically extending stakes 16 and the intermediate plates 17. The top edge of the side wall may be formed by the 'angle iron construction illustrated in cross section at 18 in Figure 3. As best shown in Figures 2 and 3, the plates 17 are provided with the central portions 19 located substantially in the planes of the outer faces of the stakes 16. The portions 19 of the plates are connected by the sloping portions 20 to the lat edge porti-ons 21 which latter are located substantially in the plane of the inner face of the stakes 16. As shown in Figure 2 the overlaplped edges 21 are secured by rivets 22 to t e stakes 16. This overlap forms a double thickness of metal which serves to reenforce and strengthen the stakes.

As shown in Figure 3, the upper and lower edges 22 and 23 of the plates are also located in the plane of the side edges 21. As shown at the right of Figure 1 the end plate 17 is only dished outwardly in part and is provided with a flat portions 25 so that the adder rungs 26 may be secured to the plate without extending outwardly beyond the plane of the outer face of the stakes.

' By the construction shown the cubic capacity of the car is materially -.increased without increase in over-all dimensions. Further, the stakes are reenforced and are -protected by the outwardly extending wall sections, and the dished construction adds rigidity to the wall plates. While this form of construction has been shown as applied to one particular t of hopper car, 1t is to be understood that contemplate its use in connection with other t pes of cars within the spirit and scope o the accompanying claims.

I claim:

1. In a railway car, a wall construction comprising stakes, a wall portion between the stakes, said wall portion having lts entire outer face substantially /in the plane of the outer face of the stakes and being provided with inturned edges attached to the stakes.

2. In a railway car, wall construction coinprising supporting stakes, a. wall portion extending between the stakes, said wall portion having its entire outer face substantially in the plane of the outer face of the stakes and being provided with inturned edge portions attached to the inner face of the stakes.

3. In a railway car, wall construction coluprising supporting stakes, a wall portion between the stakes, said wall portion coinprising a plate having its edges tunned inwardly and secured to the inner face ot' the stakes,

the remainder of the wall portion being sub-I stantially in the plane of the outer face of the stakes. 4. In a railway car, wall construction comprising stakes having laterally extending anges, a wall portion comprisin a plate having its entire central portion dlshed outwardly substantially to the plane of the outer face of the stakes and inwardly and laterally extending edge portions attached to the inner face of the stake flanges.

5. In a railway car, a wall portion eomprising a plate having a width to extend between a stake of the car side and the next adjacent stake, said plate having its edges turned inwardly to form flanges for attachment to the stakes and also forming a main wall substantially filling the space between the adjacent stakes in substantially the piane of the outer face of the stakes.

6. In a railway car, a wall comprising stakes, a wall portion bridging the space between the stakes, said wall portion having substantially its entire outer face at or near the plane of the outer face of the stakes and being provided with inturned portions at the stakes for attachment thereto.

7. In a ear of the class described, the usual stakes and a wall having substantially its entire main portion in a plane at or near the outer face of the stakes and being provided with intermediate portions at or near the inner face ofthe stakes attached thereto.

Signed at Chicago, Illinois, this 24th day of May, 1926.
